WATER-MOTOR.

To all whom it may concern:

Be it known that I, J onN H. I'IENDRICK- SON, a citizen of the United States of America, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in lVater-Motors; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in water motors, and especially to devices of this character for operating domestic washing machines.

The object of this invention is to provide a motor of this character which will be compact in form so that it can be conveniently mounted on a tub, which will be economical in the use of water and which will require no attention during its operation.

My invention, therefore, consists in the features of construction, and combination of parts as described in the specification, pointed out in the claims and illustrated in the accompanying drawings.

In the accompanying drawings, Figure 1 is an end elevation of the tub provided with a motor embodying my invention. Fig. 2 is a view showing the tub in central section and the motor in end elevation. Fig. 3 is a side View of the motor partly in section.

Again referring to the drawings, 1 indicates the tub or water receptacle which is semi-cylindrical in form and is provided with suitable supports 2. In the bottom of the tub is arranged a drainage outlet 3 which is closed by a stopper 1. The drum 5 for holding the clothes is supported by means of trunnions 6 which rest in semi-circular bearings 7 formed in the side of the tub. The trunnions 6 are held in the bearing 7 by means of straps 8. Each of the straps S is pivotally secured at one end to the tub and in the opposite end of the strap is formed a slot 9. A bolt 10 is pivotally secured on each side of the tub and is arranged to enter the slot 9 in the strap 8, and on the upper end of the bolt 10 is arranged a thumb-screw 11 so that by screwing down on the thumbscrews the straps 8 are secured over the trunnions, or by loosening the thumb-screws the bolts can be swung out of their slots permitting the straps to be raised and the clothes drum to be removed from the tub.

Specification of Letters Patent.

Application filed December 20, 1907, Serial No. 407,279. Renewed December 11, 1909.

Patented Apr. 12, 1910.

Serial No. 532,677.

The clothes drum is provided with an opening 12 having a hinged cover 13.

The tub is provided with a semi-cylindrical hinged cover 1 1. On one end of the tub is secured a plate 15 on which is mounted a cylinder 16 which is closed at its ends by heads 17 and 18. \Vithin the cylinder is arranged a piston which, preferably, consists of two circular plates 19 and 20 which are secured together by screws 21. Piston rods 22 and 23 are formed integral with the respective plates 19 and 20. The piston rods 22 and 23 are made sufficiently long so that they will at all times project at the ends of the cylinder 16 and where the rods extend through the said cylinder they are provided with suitable packing glands 24:. Above and extending longitudinally of the cylinder 16 is arranged a rack 25, the ends of which rest on and are secured to the ends of the piston rods 22 and 23. On the cylinder 16 are formed guideways 26 in which the rack 25 travels. On the adjacent trunnions 6 of the clothes drum is secured a gear wheel 27 which is arranged to mesh with the rack 25. It will therefore be understood that when the piston is forced to one end of the cylinder 15 the rack will travel in the same direction rotating the gear wheel 27 and consequently rotating the clothes drum and when the piston is forced to the opposite end of the cylinder the rack will again move with it, and the gear wheel 27 and the clothes drum will be rotated in the opposite direction to that in which they were first rotated. Below the cylinder 16 is arranged a casting 29 which is secured to said cylinder by screws 30 and in said casting is formed a valve chamber 31, an intake chamber 32 which communicates with the valve chamber at the top thereof, a drainage chamber 33 which communicates with the valve chamber at the bottom thereof and two passage-ways 3 1 and 35 which communicate with the valve chamber at diametrically opposite sides thereof and with the cylinder 16 at the respective ends thereof.

In the valve chamber 31 is mounted a valve 36 and the arrangement of the valve is such that when it is in one position it will establish communication between the intake chamber 32 and passage-way 34 and between the drainage chamber 33 and the passageway 35 and when in its other position it will establish communication between the intake lid chamber 32 and the passage-way 35 and the drainage chamber 33 and the passage-way 34. A water supply pipe 44 is connected with the intake chamber and a waste pipe is connected with the drainage chamber. Therefore when the valve 36 is in the position shown in Fig. 3 the water from the supply pipe will enter the intake chamber 32 and then pass through the valve chamber 31 and through the passage-way 34 and exert a pressure on the piston in the cylinder 16 which will cause the piston to move toward the opposite end of the cylinder and the water in the cylinder will be forced through the passageway 35 and the valve chamber 31 into the drainage chamber 33 from whence it will pass out through the waste pipe 45.

The mechanism for controlling the operation of the valve 36 is actuated by the water from the supply pipe 44 and is mounted and arranged as follows, On the casting 29 is formed bracket or support 3'7 and on this bracket is mounted a vertical cylinder 38 in which is arranged a piston 39 having a piston rod 40 which extends down and is connected with the valve 36 by an arm 41, so that as the piston moves up and down in said cylinder it will bring the valve to one or the other of its operative positions. The cylinder 38 is provided with a suitable packing gland 42. At the side of and preferably formed integral with the cylinder 38 is arranged a valve casing 46 which communicates with said cyhnder 38 through passag ways 4'7 and 48 at the upper and lower ends of said cylinder. The valve casing 46 is connected with the outlet chamber 33 by a pipe 50 which extends from the lower end of the valvecasing and with the intake chamber by a pipe 49 which extends from the side of the casing.

In the valve casing 46 is arranged a balanced valve comprising a hollow rod on which are arranged two valves 53 and and the arrangement thereof is such that one of the valves will always be above and the other below the mouth of the pipe 49. it drainage opening 55 is formed in the rod above the valve 52 is mounted a roller 56 and on the opposite ends of the rack 25 are arranged two oppositely disposed cams 57 and 58. The cam 5? is arranged to pass under the roller 56 when the rack 25 is nearing the end of its travel in one direction and thereby raise the valve rod 52 and establish comn'mnication between the pipe 49 and the cylinder 38 through the valve casing 46 and the passage-way 47 so that water from the intake chamber 32 will enter the cylinder 38 above the piston 39 and at the same time it establishes communication between the pipe 50 and the cylinder 38 through the passage-way 48 so that any On the end of the rod into the drainage chamber 33. The cam 58 is arranged to pass over the roller 56 and thereby depress the valve rod when the rack is near the end of its travel in the opposite direction thereby establishing communication between the pipe 49 and the cylinder 38 through the passage-way 48 so that water from the intake chamber 32 will enter the cylinder 38 below the piston 39 and also establishing communication between the pipe 50 and the cylinder 38 through the valve casing, through the valve rod itself and the passage-way 47 so that water above the piston 39 will drain out through the passage\vay 47 into the valve casing above the valve 52 then through the opening 47 in the valve rod and through the valve rod into the lower part of the valve casing and thence through the pipe 50 into the drainage chamber 33.

The general operation of the device is as follows,The clothes to be washed are placed in the drum l4 and if we assume that the machine was stopped in the position shown in Fig. 3 then when the water is turned on it will enter the intake chamber 32 and divide, part flowing through the passage-way 34 and into the cylinder 16 behind the operating piston and will cause the piston to move to the opposite end of the cylinder carrying with it the rack 25 and thereby rotating the gear 27 and consequently rotating the clothes drum and part of the water will flow through the pipe 49 and into the cylinder 38 above the piston 39, but as the piston is already in its lowest position it will produce no movement of the piston at this time. As the rack 25 nears the end of its travel the cam 58 will pass over the roller 56 shoving down the valve rod and as soon as the valve 54 passes below the passage-way 48 water from the intake chamber 32 will enter the cylinder 38 below the piston 39 producing an upward movement of said piston 39 and before the rack 25 ceases to move in the direction in which it was traveling the piston 39 will have been forced to the top of the cylinder 38 carrying up the piston rod 40 and the arm 41 and thereby rotating the valve 36 so as to establish communication between the intake chamber 32 and the passage-way 35 and between the drainage chamber 33 and the passage-way 34. The water will now pass from the intake chamber 32 through the pas sage-way 35 into the cylinder 16 at the opposite end thereof forcing the piston to move in the opposite direction through the cylinder and consequently driving the rack in the opposite direction and again rotating the gear 2' and the clothes drum.
